Zirconium is a lustrous, greyish-white, soft, ductile, malleable metal that is solid at room temperature, though it is hard and brittle at lesser purities. In powder form, zirconium is highly flammable, but the solid form is much less prone to ignition. Zirconium is highly resistant to corrosion by alkalis, acids, salt water and other agents.
Zirconium is also used to make superconductive magnets. Zircon (zirconium silicate, ZrSiO 4) is a natural gemstone and synthetic cubic zirconia (zirconium dioxide, ZrO 2) is produced as a low-cost substitute for diamond. Zirconium based catalysts are used in amination, hydrogenation, isomerization and oxidation reactions.

Zirconium dioxide (ZrO 2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium.Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite.A dopant stabilized cubic structured zirconia, cubic zirconia, is synthesized in various colours for use as a gemstone and a diamond simulant.
The present invention relates to novel microporous zirconium silicate compositions that are formulated to remove toxins, e.g. potassium ions, from the gastrointestinal tract at an elevated rate without causing undesirable side effects. The preferred formulations are designed avoid increase in pH of urine in patients and/or avoid potential entry of particles into the bloodstream of the patient.
It occurs in nature as the silicate (ZrSiO 4) and is used as a gemstone; it may be clear or colored, and is usually called zircon or hyacinth. Zirconium compounds also have minor uses as catalysts, in the dye, textile, plastics, and paint industries, and in pharmaceuticals such as poison ivy lotions.

How-' ever, the preferred formula does contain 20% zirconium silicate because the surface hardness is increased, and from 5% to 25% of zirconium silicate may be used, desirably for this purpose. Other refractory materials among those mentioned above may be used to replace zirconium silicate in whole or in part with similar beneficial results.

Zirconium, symbol Zr on the Periodic Table, is a metal most often found in and extracted from the silicate mineral zirconium silicate and the oxide mineral baddeleyite. In its various compound forms, the grayish-white zirconium is the nineteenth most plentiful element in the earth's crust, where it is far more abundant than copper and lead.

Zirconium silicate is the best opacifier for frits in terms of cost and properties. It also has glass forming abilities as an intermediate element, it is a network former with coordination 4. Zirconium can remain in the glass network when the frit is quenched, but this status is not stable.
Zirconium beads go by many names around the world: Mahlperlen in Germany. Bolas de Moliendas in South America. Pearls in Europe. Zirconia beads in Asia. But whichever corner of the globe you call home, whatever you call the beads, one thing is clear—FOX Zirconium Silicate Grinding Media is the right ceramic grinding media for you.
Zirconium silicate, also zirconium orthosilicate, (Zr Si O 4) is a chemical compound, a silicate of zirconium. It occurs in nature as the zircon, a silicate mineral. Zirconium silicate is usually colorless, but impurities induce various colorations. It is insoluble in water, acids, alkali and aqua regia. Hardness is 7.5 on the Mohs scale.

The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.
Individual zircon particles are angular, very hard and refractory and amazingly, they do not readily dissolve into glaze melts even when ball milled to exceedingly small particle sizes. Zircon is the generic name for zirconium silicate, the trade names are different (for example, Zircopax, Zircosil).
